Answer:
C) 78,200
Step-by-step explanation:
If p represents the population in 2010, then the population in 2012 is ...
p + 0.30p = 1.30p
and the population in 2014 is ...
(1.30p) + 0.20(1.30p) = (1.30p)(1.20) = 1.56p
This is the same population as in 2015, so we have ...
1.56p = 122,000
p = 122,000/1.56 ≈ 78,200 . . . . rounded to hundreds
In 2010, the population of Maple Mall was about 78,200.
Answer:
∠1=160° and ∠2=20°
Step-by-step explanation:
Let ∠1 = x
∠2 = y
as these two angles are supplementary their sum is 180
that x+y=180 ----(A)
Also given that ∠1 is 20 degree less than nine times the size of ∠2.
Hence
x=9y-20
putting value of x in A and solving for y
9y-20+y=180
10y=180+20
10y=200
y=10
Putting this y in A
x+10=180
x=160
